I need a logo for my website, my business card, my letters etc. It is logo for my family holding company/investment company. Therefor I need a family logo/family crest - elegant (old?) style. Made in gold finished, elegant, old style. Include in some way, maybe shipping (anker), planes (propell) stocks, property and a snake (viper). In a smart way. If we are happy with the result, we can go further with other needs.
